Quick Start Guide
Click to enter the preset menu
incl. save, save as default,
copy/paste presets or copy
plugin states
Choose between 5 GUI-sizes. Right click to
switch to a bigger size. Right click while
holding down Alt switches to a smaller size.
Previous preset
Choose between 3 models:
MK 1: inspired by early
variable-mu designs with
very gentle compression
characteristics and lots of
vibe.
MK2: more obvious, forward
sounding compression based
on american designs from
the 60s.
Mk3: modern interpretation
of the variable-mu topic.
very flexible and punchy
Click to switch between two plugin
states.
To copy one state to the other enter the
preset menu and select “copy A to B” or
“copy B to A” depending on which state
is active.
NOTE: the states aren't saved with your
session. When re-opening, both states
are set to the plugin state you've saved
with the plugin instance in your session.

Automatic gain compensation
(auto-makeup):
The calculated MakeUp level is
based on the RMS-difference
between input level and
compressed signal. If gets
recalculated (and applied) every
time when a gain reduction
affecting control is changed. This
calculated makeup level is saved
with the session. It's
recommended to leave it off when
using automation, since it might
lead to undesired result when
automating.
Click to en-/disable
high quality
processing
(oversampled and
more accurate
models)
Sets the reference
level not only for the
VU meter but also for
the entire signal path.
Click to enter a value.
If you click at the
“CAL” label use can
also drag the mouse
to change the
calibration level. Or
position the mouse
pointer over the CAL
label and use the
mouse wheel.
NOTE: when using AGC you can
still fne-tune the output level with
the make-up control

Sets the behaviour of the
gain reduction meter (when
the VU-meter is set to GR).
When set to SLOW, the gain
reduction is shown with the
timing constants of a
standard VU meter. When
set to fast, the GR meter
acts like a peak gain
reduction meter.

Workflow and Preset system
WORKFLOW:
1. make sure, that your input signal hits around 0dBVU. This is the optimal working level for MJUC.
2. use the COMPRESSION to adjust the compression to taste.
3. use the MAKE-UP control to compensate for any volume loss caused by the compression.
PRESETS:
Use the arrow buttons to select the previous/next preset or click in the preset feld to select a preset from the
drop down menu.
To save your own default setting, click on the preset-feld, then choose save->save as default.
Please note that the GUI size is saved here too. So you can defne your preferred GUI size here, which is recalled
when opening a new plugin instance.
User Presets Path:
Windows: C:\Users\<username>\AppData\Roaming\Klanghelm\MJUC\UserPresets
OSX: /Users/<username>/Library/Klanghelm/MJUC/UserPresets
Location of the Default State:
Windows: C:\Users\<username>\AppData\Roaming\Klanghelm\MJUC\default.xml
OSX: /Users/<username>/Library/Klanghelm/MJUC/default.xml
If you want to revert to the FACTORY default settings, simply delete the default.xml fle from your HDD
